Abstract

This paper proposes innovative control schemes for Pelton turbines to improve frequency regulation in isolated power systems with high penetration of variable renewable energy sources (vRESs). Traditionally, Pelton turbine deflectors are used as safety mechanisms; however, this study explores their potential for continuous frequency regulation, alongside the conventional needle control. The proposed strategies, including a deflector-based control and a mixed control (combining both injector as well as deflector actions), aim to address the limitations of traditional methods. The results obtained from dynamic model simulations demonstrate significant improvements in system performance and stability compared with the traditional needle-based control. In particular, the mixed control strategy achieves a balanced solution, minimizing frequency deviations, reducing water losses, and maximizing renewable energy integration. These findings highlight the potential of advanced turbine control to optimize the operation of isolated power systems and support the transition to sustainable energy systems.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-26:

  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 1 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

    It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

    • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
